alright guys, i'm getting these for the H22

if i'm ever not poor, but i was wondering what would be the advantages or disadvantages of one size over the other, 50 versus 52MM

this will be on a fully built bottom end and a fully built head with high compression pistons, and i know this isn't honda tech, but its not about that, i'm just wondering about TB sizing

 

I lifted this off of another site.
Choice of bore size is a balanced compromise resulting from the following;
1) A larger bore leads to lower flow resistance, but obeying the laws of diminishing returns.
2) A smaller bore leads to better throttle control and response (never underestimate) and improved fuel mixing.
3) The system should be considered in total - from (at least) trumpet flange to cylinder and proportioned accordingly.

a 50mm ITB should be fine. IMO #3 on the list above is more important than a 50mm or 52mm diameter.

 

i would get them from TWM and here is what they say
but i think these are nifty, but i don't know the price

 

For the money I personally think you would be better off investing into a port & polish job from portflow or alanz & simply going with a ported intake manifold which is port matched etc.

ITBs are not practicle for a daily application in my opinion.

I have yet to see a Bseries 1.8L or Hseries 2.2L honda applications with ITBS really impress me except complete race applications.

 

why wouldn't it be?

not that i don't believe you, just wondering

 

really?

i figured that'd be the difference between the 50 and 52, is it still too big?

yeah, i don't want no bottom because this will just be a daily and the occasional auto-x so that would kinda screw meall around...damn
